Title: Improvements in and relating to thermionic valves and circuits therefor
IPC: H01J21/02
Filed: 1934-09-06
Abstract: 443,906. Thermionic valves. BULL, C. S., 33, Micawber Avenue, Hillingdon, Middlesex. Sept. 6, 1934, No. 25714. [Classes 39 (i) and 40 (v)] In a circuit for mixing incoming oscillations with locally generated oscillations, a thermionic valve acting simultaneously as oscillator and mixer has a first control electrode cooperating with an auxiliary anode on the same side of the first control electrode as the cathode to generate the local oscillations and a second control electrode receives the incoming oscillations and is arranged between the first control electrode and the main anode. A long, indirected heated cathode k, Fig. 1, of rectangular cross-section co-operates at its main emissive faces 1 with the oscillator grid g<1> and the second control grid g<4> and at its small emissive faces 2 at right angles to the faces 1 with the oscillator anode in the form of one or more small rods or wires g<2> arranged in the central plane of the cathode. Positive screening grids g<3>, g<5> may be provided and secondary emission from the main anode A may be suppressed by a further grid or other means. Corresponding electrodes on opposite sides of the cathode are connected together or form opposed parts of oval electrodes surrounding the cathode, or the electrodes on one side of the cathode may be omitted. The anode rod g<2> may be inside or outside the plane containing the support rods of the grids. The grids may be provided with solid portions 17, 18, Fig. 5, tending to focus electrons turned back by the grid g<4> on to the faces 1 of the cathode k. The mutual conductance of the anode g<2> with respect to the main anode A is less than one-tenth of that of the grid g<1> with respect to the anode A. When the grid g<1> is at or just below cathode potential and the grid g<3> and anode g<2> are at the same suitable positive potential, the current to anode g<2> is much less than that to grid g<3>. Locking of the local oscillation with the incoming oscillations is avoided. Specification 437,804 is referred to.

Title: Improvements in or relating to the production of crystal starch
IPC: C08B30/00
Filed: 1947-09-23
Abstract: 665,542. Starch. STEVENS, A. H. (Corn Products Refining Co.). Sept. 23, 1947, No. 25808/47. Drawings to Specification. Class 121. Starch from which crystal starch may be formed by drying is obtained by filtering a starch slurry so as to provide a filter cake of uncoalesced starch having a moisture content between 42 and 55 per cent and vibrating the uncoalesced filter cake so as to form it into a block of coalesced starch suitable for drying to crystal starch. The starch may be obtained from maize, potato, rice, sorghum, tapioca or wheat. In a preferred method, a starch slurry is treated with dilute suphuric or nitric acid and then heated and neutralized with soda ash. It is filtered, dried to the required moisture content and then treated at 1200- 3600 vibrations per minute with an amplitude of 1/32-3/32 inch for one or two minutes in a box lined with filter cloth. The starch is then broken up for drying.

Abstract: 301,996. Pictorial Machinery, Ltd., and Harris, R. Sept. 30, 1927. Hand-wheels.-In apparatus wherein a unit such as a negative is pressed against a lightsensitive surface, the application of excess pressure is rendered impossible by a construction of the pressure-device comprising a shaft arranged to actuate the pressure plate carrying the unit, a dished hand-wheel for, rotating the shaft, and a resilient control device, located within the concavity of the hand-wheel, and connecting the shaft to the operating member in such a manner that when the resistance to rotation of the shaft reaches a predetermined value, slip will occur between the shaft and the operating member if actuation of this is continued. In the form shown, the shaft 10, which actuates the pressure plate (not shown) through bevel gearing, carries a fixed collar 11 bearing against one of the bearings of the shaft 10. The operating member comprises a dished hand-wheel 12, the boss 13 of which rests against the collar 12 and is coupled to the shaft 10 through a slip clutch 14, 15, preferably a dog clutch having only one tooth, the element 14 being fixed to the boss 13 and the element 15 being splined on the shaft 10. On the screw-threaded upper end of the shaft 10 is a stop nut 26 for an adjusting nut 24 between which and the clutch element 15 is a coil spring 25. A slit 27 and screw 28 in the nut 24 permit the nut to be locked in adjusted position. A clockwise rotation of the wheel 12 applies increasing pressure to the pressure plate until the limit predetermined by the setting of the nut 24 is reached, whereafter the inclined faces 22 of the clutch cause the elements 14, 15 to move apart, so that the element 14 slips round the element 15 of rotation of the wheel 12 is continued.

Title: Improvements in or relating to control or protective apparatus for use with electric-circuit interrupters
IPC: H02H3/247
Filed: 1930-09-01
Abstract: 361,016. Protective cut-out systems and electrically released switches. SHEPHERD, G. R., 2, Norfolk Street, Strand, London.- (Westinghouse Electric & Manufacturing Co. ; East Pittsburg, U.S.A.) Sept. 1, 1930, No. 26026. [Class 38 (v).] In a protective arrangement including a circuitbreaker which is tripped or released when the voltage in the circuit falls below a limiting value in order to prevent the opening of the circuit in response to a temporary diminution of voltage the current in the releasing circuit is caused by electromagnetic inertia to persist for a predetermined time interval after the voltage of the circuit has fallen below this value so that the release of the circuit-breaker is correspondingly delayed. As shown, a voltage transformer 9 connected across the supply 2, 3 is arranged with voltages above the limiting value to energize a relay 12 which completes at contacts 13 a circuit for the holding coil 4 of the circuit-breaker 1 which is fed through a bank of dry plate rectifiers 11 and includes a choking coil 18. Additional current through the choking coil passes through a resistance 21 connected by contacts 15 of the relay 12. When the relay 12 is de-energized it is released and the supply for the retaining circuit is broken but the current in the coil 4 persists for a time owing to the discharge of the choking coil through an adjustable resistance 19 the circuit of which, in series with the coil 4, is completed at contacts 14 of the relay 12. To prevent the breaking of the circuit of the coil 4 while the relay 12 is changing over its contacts a further discharge path is provided through a rectifier 23 in series with a resistance 22 and the maintenance of current in the coil 4 is assisted by a condenser 24. To provide an instantaneous manual release of the circuit-breaker a press-button switch 31 may be arranged as shown so that on depression the holding coil 4 is shortcircuited by a resistance 32. A similar release may also be effected by an overload relay 35 fed from a series transformer 37. The coil 4 may be arranged, for emergency purposes, to be fed directly from the secondary of the transformer 9 by changing over the control switches 28, 29. In an alternative arrangement, Fig. 2 (not shown), the rectifying arrangements may be dispensed with, the D.C. circuit for the coil 4 being fed from an auxiliary battery.

Title: A vehicle with a device for counter-acting the inclination of the vehicle body when travelling in a curve
IPC: B60G17/019
Filed: 1938-09-09
Abstract: 518,848. Preventing lateral tilting of vehicles. MULLER, H. Sept. 9, 1938, No. 26346. Convention date, Sept. 9, 1937. [Class 108 (ii)] Apparatus for counteracting tilting of a vehicle when rounding curves by means of a pressure medium supplied from a central source to cylinders which with their pistons are connected in parallel to the vehicle springs on opposite sides of the vehicle to load the inner springs and relieve the outer ones.is characterised by using a non-compressible liquid in a system exerting resilient counteracting forces to permit yield to an extent corresponding with the spring movement. Fig. 2 shows the springs 5 and 6 at each end of an axle of the vehicle supplemented by pistons 12 and 13 in cross-connected cylinders 14 and 15 having pipe connections 16 and 17 with a valve cylinder 19. The pressure side of a toothed wheel pump 24 driven by the vehicle engine is connected by a conduit 23 with a space 18 in the valve cylinder, and its suction side with a space 25. A slide valve 20 working in the cylinder is connected with' a pendulum 22, and normally, during straight travel, a port 29 in the valve provides a communication between the spaces 18 and 25 by way of a passage 28 and a cylinder 30<1>. moreover both pipe connections 16 and 17 are in communication with the space 18 so that the pistons 12 and 13 move freely in their cylinders. On entering a curve the pendulum 22 either raises or 'lowers the valve 20 which closes the connection between the valve spaces 18 and 25 by way of passage 28 and opens a connection through itself from space 25 to either of pipes 17 or 16 whilst leaving the other pipe in communication with the pressure space 18. The tendency of the vehicle body to tilt is consequently opposed by the action of the pistons 12 and 13 acting in opposite directions. Springing of the vehicle is effected by a piston 30 subject to a compression spring 31 whilst the pistons 12 and 13 are in action. Alternatively springs may be interposed between the pistons 12 and 13 and the vehicle axle. A restricted opening controlled by an adjustable valve 27 maintains a permanent connection between the valve spaces 18 and 25 to equalize the pressure during slow travel. Valve 27 may be adjustable manually, by means of a pendulum subject to centrifugal force or by means of a connection with the steering gear. The valve 20 may, alternatively, be operated by the steering gear, cr by laterally movable members operable by the driver's foot and located on either side of a pedal actuating a pump which replaces the power driven pump 24. In a further modification rotating vanes working in cylindrical casings are employed in place of the pistons 12 and 13, each pair of vanes being connected by torsion rod and radius arm to an end of the axle. A single casing with rotating vanes may be employed, the casing being similarly connected to one end of the axle and the vanes to the other end.
